Logo is all about moving the turtle... you give it
commands
[1] like this:

Forward 100
Right 45

You can do stuff like repeating commands too:

Repeat 8 [Forward 100 Right 45] ; Draw an octagon

(What do I win? 8-)

Whoa! Is it still around?

fd 300 // Forward
rt 90 // Right 90°
fd 300
lt 90 // Left 90°

That used to work.

I've seen a few LOGO implementations where you can use localized commands like:

NAPRZOD (FORWARD),

LEWO (LEFT),

PRAWO (RIGTH)

or even NAPRZÓD (with Polish letter Ó).

LOGO is nice language to teach kids programming in their native spoken language.

try: bk(back), fd(forward), ld(left turn in degrees), rt(right turn).

By issuing commands in the correct syntax. E.G.:

forward 100

There is only one necessary command to move the turtle. It is forward which has the mnemonic fd. When working with a robot (real) turtle as opposed to a graphics based (virtual) one, you might find that the turning commands left and right [lt & rt] move the turtle a little, accidentally.
